This vast dark energy literature has prompted the study of cosmological singularities in a wide range of cosmological backgrounds as well, as there have been multiple works which have discussed Type I-IV singularities in various cosmologies [1]}, [2]}, [3]}, [4]}, [5]}, [6]}, [7]}. But Type V or w singularities have not been studied in the context of cosmological backgrounds which are not primarily general relativistic. This encourages one towards an endeavour which tries to understand the status quo of w-singularities in non-standard cosmologies, which we will be undertaking here. We will consider cosmologies which have a wide range of motivations, ranging from String theory to modified gravity theories, and we will explore under which conditions w-singularities can occur ( if they even will) in these scenarios and if these conditions are any different than what happens in the standard general relativistic case. In Section II, we will be briefly describing the cosmologies we want to consider here and in section III we will work out the conditions for w-singularities to occur in these scenarios. We will finally conclude our work in section IV.
